Abstract

The application provides a vehicle arresting device, which comprises an anchoring member fixedly installed at the end of a loading vehicle, a pushing device installed on the anchoring member, and a moving assembly. The moving assembly is pushed by the pushing device to approach a target vehicle in parallel to the driving direction of the loading vehicle, to constrain the driving wheels of the target vehicle and limit the distance between the target vehicle and the loading vehicle. Thus, the application can only intercept a specific target vehicle driving on the road by using the loading vehicle, without causing interference to other vehicles driving on the road. The interception mode of the application mainly constrains the driving wheels of the vehicle, thus without damaging the target vehicle, and can keep the target vehicle in a specific distance range by the moving assembly, so as to effectively avoid secondary accidents caused by improper operation of the driver when the target vehicle is intercepted. The application can ensure the safe driving of the target vehicle and the loading vehicle, and protect the drivers on both vehicles.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle-mounted devices, in particular to a vehicle arresting device. BACKGROUND

[0002] When it is necessary to intercept a vehicle in motion, the existing method usually needs to arrange an obstacle or an intercepting device in the road. However, such an intercepting device needs to occupy a lane, and usually indiscriminately intercepts vehicles on the lane where it is located, thus easily intercepting non-target vehicles by mistake.

[0003] In order to intercept a target vehicle that illegally or dangerously drives, if a conventional tire puncture device is used, a secondary accident is likely to occur, which seriously threatens the safety of people's lives and property.

[0004] Therefore, it is necessary to provide an arresting device that can accurately intercept a target vehicle and does not cause the running direction of the vehicle to be uncontrollable. SUMMARY

[0036] The terms "up" and "down" as used in this application refer to the direction from the ground toward the pushing device when the operator is facing the direction of the loading vehicle's movement, and vice versa, rather than a specific limitation on the device mechanism of this application.

[0037] The vehicle capture device provided in this application can be installed on a vehicle and intercepts the target vehicle through the following structure:

[0038] Anchoring component 2 is fixedly installed at the end of the loading vehicle 1, for example, on the front bumper of the loading vehicle or at the rear of the loading vehicle.

[0039] The pushing device 3, which is installed on the anchoring member 2, can push the action component 4 along the driving direction of the loading vehicle 1. For the vehicle catcher installed on the front bumper, the pushing device 3 can pop forward in the driving direction to drive the action component 4 to intercept the target vehicle in front of the loading vehicle; for the vehicle catcher installed on the rear, the pushing device 3 can pop backward in the opposite driving direction to drive the action component 4 to intercept the target vehicle behind the loading vehicle.

[0040] The actuating component 4 can be configured as a flexible material to wrap around and restrain the driving wheels of the target vehicle, or as a rigid component to lift the driving wheels of the target vehicle off the ground, thereby restricting the driving of the target vehicle. Regardless of the type of actuating component 4, it can be configured to be pushed by the pushing device 3 to approach the target vehicle 5 along the driving direction of the loading vehicle 1, restrain the driving wheels of the target vehicle, and limit the distance between the target vehicle and the loading vehicle.

[0041] In the first implementation, this application can adopt Figure 1 The shown winding mesh structure achieves the aforementioned interception and capture function. Specifically, the vehicle capture device can configure the propulsion device 3 as follows:

[0042] The storage device 33 is fixedly installed at the end of the anchoring member 2 such as the steel frame. Specifically, the storage device 33 can be configured as a frame structure to accommodate the moving component and the following structure.

[0043] A retractable rod 31 is rotatably mounted at the bottom of the storage device 33 via a connecting shaft 32;

[0044] The telescopic launcher is installed between the storage device 33 and the retractable rod 31. It compresses and stores energy when the retractable rod 31 is rotated closed relative to the storage device 33, and extends and pushes out the action component 4 when the retractable rod 31 is rotated open relative to the storage device 33.

[0045] Meanwhile, in conjunction with the aforementioned propulsion device 3, the vehicle catcher can configure the actuation component 4 as follows:

[0046] The winch 42 is mounted on the anchoring member 2 and installed between the receiving device 33 and the anchoring member 2.

[0047] The steel rope 41 is connected to a winch 42 at one end and is driven by the winch 42 to be retracted to the storage device 33.

[0048] The winding net 43 is connected to the other end of the steel rope 41. In the retracted state, the winding net 43 is housed between the telescopic launcher and the retracting rod 31. When the retracting device 33 is rotated open, the winding net 43 is ejected by the telescopic launcher in the direction of travel to wrap around the wheels of the target vehicle. Then, the winch 42 drives the steel rope 41 to retract.

[0049] Therefore, the aforementioned entanglement net vehicle catcher can restrict the rotation of a target vehicle by wrapping the entanglement net 43 around its wheels in the following manner: First, the loading vehicle approaches the target vehicle, then maintains a distance from the target vehicle. When the target vehicle reaches the launch range of the telescopic launcher, the storage device is opened, driving the telescopic launcher forward to eject the entanglement net so that it can wrap around the rear wheels of the target vehicle. Subsequently, the winch is tightened, driving the steel cable to pull the entanglement net backward, restricting the target vehicle from continuing to move forward until its wheels are entangled and locked, thus braking the target vehicle.

[0050] In the second implementation, this application can adopt Figure 2 The strap-type structure shown achieves the aforementioned interception and capture function. Specifically, the vehicle capture device can configure the propulsion device 3 as follows:

[0051] The hydraulic cylinder is fixedly installed at the bottom of the anchoring member 2 and has a telescopic direction parallel to the driving direction of the loaded vehicle. For the vehicle catcher installed on the front bumper of the vehicle, its hydraulic cylinder can be set to drive the telescopic rod to extend forward to approach the target vehicle and achieve braking restriction; for the vehicle catcher installed at the rear of the vehicle, its hydraulic cylinder can be set to drive the telescopic rod to extend backward to approach the target vehicle behind and achieve braking restriction.

[0052] Meanwhile, in conjunction with the aforementioned propulsion device 3, the vehicle catcher can configure the actuation component 4 as follows:

[0053] The telescopic rod, which is connected to the telescopic end of the hydraulic cylinder, is driven by the hydraulic cylinder to extend outward or retract directly from the chassis;

[0054] Nylon straps 44 are fixedly installed at the far end of the telescopic pole, extending outward along with the telescopic pole to get close to the road surface, wrapping around and restraining the wheels of the target vehicle.

[0055] The actuation component of this application does not require a winch and frame, but instead directly contacts the front wheel through the nylon straps on the telescopic rod to achieve braking.

[0056] Generally, this vehicle capture device can have the hydraulic cylinders respectively installed on the left and right sides of the loading vehicle, including at least two, or three or four, to restrict one side of the target vehicle's wheels and change its direction of travel; each hydraulic cylinder is equipped with a telescopic rod at its end; the telescopic rods are respectively installed on the left and right sides of the loading vehicle, and each telescopic rod is synchronously driven by the hydraulic cylinder to extend outward or retract inward; the nylon strap 44 is fixedly connected between two adjacent telescopic rods, and extends outward along with the telescopic rods to get close to the road surface, wrapping around and restraining the target vehicle's wheels.

[0057] To prevent the deformation of the telescopic rod ends during contact with the target vehicle's wheels from affecting the unfolding of the nylon straps, this application preferably provides a rigid connecting rod 45 between adjacent telescopic rods, specifically at the ends of the telescopic rods. The connecting rod 45 is parallel to each nylon strap 44 and is located at the farthest end of the telescopic rod, which can limit the distance between the telescopic rods during contact with the target vehicle's wheels.

[0058] Under the third implementation provided in this application, this application can be improved. Figure 2 The strap-type structure, through Figure 3 The above-mentioned interception and capture functions are achieved in this way. Specifically, the vehicle capture device can configure the propulsion device 3 as follows:

[0059] The connecting shaft 32 is parallel to the loading vehicle 1 and is laterally positioned at the bottom of the anchoring member;

[0060] Channel steel 60, which can form a steel frame, one end of which can be rotatably connected to the connecting shaft 32, and the other end of which can extend outward. The entire channel steel frame can be switched to the grabbing state by the unfolding of the winch, or driven by the return spring 34 to retract so as not to obstruct the movement of the loading vehicle.

[0061] The return spring 34 has one end fixedly connected to the anchoring component and the other end fixedly connected to the channel steel 60. The return spring 34 pulls up the channel steel 60 in the contracted state and flips down the channel steel in the stretched state, so that the end of the channel steel 60 extends outward along the driving direction and is kept at a height close to the road surface.

[0062] Meanwhile, in conjunction with the aforementioned propulsion device 3, the vehicle catcher can configure the actuation component 4 as follows:

[0063] A nylon strap 44 is provided at the far end of the channel steel 60. One side of the nylon strap 44 is fixedly connected to the connecting shaft 32, and the other side of the nylon strap 44 is connected to a steel rope 41.

[0064] The end of the steel rope 41 is connected to the winch 42 and is driven by the winch 42 to extend toward the end of the channel steel 60 or retract toward the connecting shaft 32.

[0065] The winch 42 is fixedly installed at the bottom of the anchoring member 2 and is located below the connecting shaft 32;

[0066] The nylon straps 44 are released synchronously by the winch 42 as the channel steel flips downwards, and are kept at a height close to the road surface along the driving direction to wrap around and restrain the wheels of the target vehicle.

[0067] Therefore, the aforementioned strap-on vehicle catcher can restrict the rotation of a target vehicle by wrapping a nylon strap-on net 43 around the wheels of the target vehicle. When the vehicle catcher is installed on the front bumper, the target vehicle can choose the vehicle in front of it, and the actuation component 4 can wrap around the rear wheels of the vehicle in front and directly restrict its rotation, causing the rear vehicle to brake and stop the vehicle in front. When the vehicle catcher is installed at the rear of the vehicle, the target vehicle can choose the vehicle behind it, and the actuation component 4 can wrap around the front wheels of the vehicle behind it and directly restrict its rotation, causing the vehicle in front to drag and restrict its movement. The nylon straps are wrapped around the extension frame at one end, forming a parallel strip structure. The frontmost strap has a friction-increasing plate, and the other end is fixed to the vehicle chassis, leaving a certain length to be coiled inside the storage net for extending the reaction distance after the rear vehicle brakes. The extension frame includes two rotating channel steels and a cross brace. The rotating channel steels are located on both sides and connected in the middle by the cross brace. The fixed frame includes two anchoring channel steels and a cross brace. The rotating channel steels and the anchoring channel steels are connected by a rotating shaft. The end of the anchoring channel steel is anchored to the front of the vehicle. A return spring is installed between the two. The return spring has a rebound force, which causes the extension frame to fold along the rotating shaft and come into contact with the front of the vehicle. The winch is located in a box at the front of the truck. The winch has a wire rope that can be extended or retracted. One end of the wire rope is connected to the lower part of the cross brace on the extension frame. When the wire rope is retracted by the winch, the winch resists the return spring, and the extension frame is pulled to be parallel to the road surface, protruding 2m beyond the front of the truck. When the wire rope is extended by the winch, the winch follows the direction of the return spring's force, and the extension frame is rebounded by the return spring to be close to the front of the truck, while the fixed frame remains stationary.

[0068] During the interception process, considering safety factors, it is generally desirable to restrict the target vehicle to a position far away from the loading vehicle. Therefore, in this embodiment, it is preferable to configure the channel steel 60 as including at least two sets respectively installed on the left and right sides of the loading vehicle, and each set of the channel steel 60 is configured as several segments connected in sequence, with channel steel connecting rods 61 rotatably connected between each segment of channel steel 60;

[0069] The channel steel connecting rod 61 can be connected parallel to the connecting shaft 32 between two adjacent sets of channel steels 60, limiting the distance between the two sets of channel steels 60;

[0070] Each channel steel 60 can also be provided with a cross brace 62 in the middle. The cross brace 62 is parallel to the connecting shaft 32 and connected between two adjacent groups of channel steel 60, thereby limiting the distance between the two groups of channel steel 60 in the same way as the connecting rod 45.

[0071] Each group of channel steel 60 is connected to a return spring 34. The return springs 34 are respectively installed on the left and right sides of the loading vehicle. Each return spring 34 extends outward or retracts inward synchronously.

[0072] The nylon strap 44 is fixedly connected between two adjacent sets of channel steels 60 and stretches synchronously as the channel steels 60 extend outward.

[0073] The device is used as follows: 1. Install the corresponding open / close button and other control devices 11 inside the loading police vehicle. Press the open button, and the extension frame constructed by the two sets of channel steel 60 can be extended to be parallel to the road surface under the tension of the steel wire rope, and the height does not exceed the chassis of the target vehicle; 2. The loading vehicle chases the illegal target vehicle from behind. When the opportunity arises, the loading vehicle accelerates and inserts the rear wheel of the target vehicle into the extension frame; 3. At this time, the rear wheel of the front vehicle is rotating at high speed. The inertia of the wheel can cause the nylon strap to be wound into the axle position, so that the wheel is forcibly braked from the outside to stop rotating; 4. As a result, the target vehicle in front will continue to move by the driving power of its front wheel. At this time, the loading police vehicle behind the target vehicle can apply the brakes accordingly. During the braking process, the nylon strap will be pulled out of the storage net, so that the braking nylon straps of the front and rear vehicles are straightened; 5. As a result, the loading police vehicle behind continues to apply further braking force to force the front vehicle to stop moving forward, thereby achieving the purpose of braking the front vehicle.

[0074] In the fourth implementation, this application can adopt... Figure 4 Another hook-and-support structure shown achieves the aforementioned interception and capture function. Specifically, the vehicle capture device can configure the pushing device 3 as follows:

[0075] A hydraulic cylinder is fixedly installed at the lower part of the anchoring component 2. The drive output end of the hydraulic cylinder is connected to the retraction rod 31. Several levels of connecting rods are rotatably connected to the top of the retraction rod 31. Each level of connecting rod extends outward as the hydraulic cylinder lifts the retraction rod 31, and retracts back into the anchoring component 2 as the hydraulic cylinder retracts the retraction rod 31.

[0076] Meanwhile, in conjunction with the aforementioned propulsion device 3, the vehicle catcher can configure the actuation component 4 as follows:

[0077] An alloy steel hook is installed at one end of the last stage of the connecting rod, and the other end of the alloy steel hook has an upward bend. When the connecting rod is extended, the alloy steel hook extends outward along the driving direction and is kept at a height close to the road surface, preventing the target vehicle's wheels from leaving the road surface.

[0078] Therefore, the alloy steel hook can be hydraulically extended and deployed under the vehicle, and then hydraulically retracted to lift the chassis and tow away the following vehicle.

[0079] Specifically, in this structure, the frame structure of the anchoring component 2 can be fixed to the chassis of the loaded vehicle by welding or any other method. An installation groove can be provided in the middle of the anchoring frame, and the bottom of the alloy steel hook is anchored within the installation groove of the anchoring frame. The hydraulic cylinder can also be installed within the installation groove. To lift the target vehicle, the hydraulic cylinder can be configured such that one end is fixed to the anchoring frame, and the other end is connected to the top of the alloy steel hook via a multi-link rod. Thus, the hydraulic cylinder can extend and retract via its hydraulically driven telescopic rod, thereby controlling the alloy steel hook to extend horizontally forward and downward to contact the chassis and wheels of the target vehicle, or to rise and retract vertically, causing the chassis or wheels of the target vehicle to leave the road surface, cutting off its drive output, and thus preventing the target vehicle from stopping.

[0080] The vehicle capture device operates as follows: 1. Triggering the extend / retract button installed inside the loading vehicle extends the hydraulic cylinder, controlling the alloy steel hook to unfold horizontally via a multi-link mechanism, with the hook positioned below the chassis; 2. Police cars or other loading vehicles can extend the alloy steel hook into the rear chassis of the target vehicle from directly behind it; 3. Pressing the retract button again retracts the hydraulic cylinder, raising the alloy steel hook vertically via the multi-link mechanism, thus simultaneously towing the illegally parked vehicle. At this point, the police car behind the target vehicle can output power to tow the illegally parked vehicle away, achieving the purpose of moving the vehicle in front.

[0081] In the fifth, more preferred implementation, this application may adopt... Figure 5 Another, more preferred, winding mesh structure is shown to achieve the aforementioned interception and capture function. Specifically, based on the pushing device 3 of the first implementation, the vehicle capture device can be further configured to include the storage device 33.Figure 5 Shown:

[0082] A fixed arm is vertically installed at the end of the anchoring member 2, and a rotating arm is rotatably connected to the bottom end of the fixed arm via a connecting shaft 32;

[0083] The fixed arm may have a separate storage box 30 at its center. The storage box 30 has a positioning horn 301 that passes through the fixed arm. The positioning horn 301 can be connected to the connection end of the winch to facilitate the pulling of the winding net 43 and the steel rope 41. The winding net 43 and the steel rope 41 can be accommodated in the positioning horn 301 and pushed out by the telescopic launcher.

[0084] At the same time, in conjunction with the aforementioned propulsion device 3, the vehicle catcher can configure the telescopic launcher in the action assembly 4 to employ... Figure 6 The structure shown below:

[0085] Cardboard 302, which can be along Figure 6 The vertical length is set to be greater than the vertical opening width of the positioning horn 301. Simultaneously, the clamping plate 302 is positioned along... Figure 6 The width dimension in the horizontal direction is set to be less than the opening length in the horizontal direction of the positioning horn 301. Thus, when the long shaft of the clamping plate 302 is placed vertically, its upper and lower ends can be clamped onto the positioning horn 301 to limit the inner winding net 43 and steel rope 41. When the long shaft of the clamping plate 302 is switched to a horizontal position, the connection between its two ends and the positioning horn 301 can be removed, thereby releasing the constraint on the inner winding net 43 and steel rope 41.

[0086] A rotary motor is connected to the back of the clamping plate 302. Its motor output shaft can pass through the positioning horn 301 and connect to the center position of the clamping plate 302, thereby driving the clamping plate 302 to rotate to the corresponding angle in the positioning horn 301, so as to constrain the winding net 43 and the steel rope 41 or release them to intercept the target vehicle.

[0087] The launching spring has its bottom end fixedly installed at the bottom of the positioning horn 301, and its top end can be abutted and fixed by the clamping plate 302. The launching spring can push the winding net 43 and the steel rope 41 between the winch 42 and the clamping plate 302. Specifically, when the rotating motor drives the clamping plate 302 to rotate to a first angle where the long axis is vertical, the launching spring can be kept in a compressed and energy-storing state by the limiting abutment between the clamping plate 302 and the positioning horn 301; when the rotating motor drives the clamping plate 302 to rotate to a second angle where the long axis is horizontal, the two ends of the clamping plate 302 can disengage from the contact abutment with the side wall of the positioning horn 301, thereby releasing the launching spring. The winding net 43 and the steel rope 41 are pushed out from the positioning horn 301 by the extension and reset of the launching spring, launching the winding net 43 to the driving wheel position of the target vehicle and then wrapping around its driving wheel to achieve driving restriction of the target vehicle.

[0088] The positioning horn 301 can be configured as an open structure with a constricted bottom and an expanded end. The expanded opening at the end allows the wrapping net to spread outward more fully after launch, while the inward narrowing at the bottom helps to limit the clamping plate. The positioning horn can generally be configured to be wider horizontally and narrower vertically, and the clamping plate can be configured as a rectangular plate smaller than the horn. The bottom surface of the positioning horn can be welded to the spring. The rotating shaft of the rotary motor can be directly welded to the clamping plate. Before the rotary motor starts, the long side of the clamping plate is clamped to the narrow side of the horn. After the rotary motor starts, the clamping plate rotates around the rotating shaft. When the clamping plate is fully rotated within the horizontal range of the horn, it can break free from the restriction of the side walls around the horn, so that the clamping plate does not jam against the horn. At this time, the rotating shaft can be driven by the elasticity of the launch spring to move horizontally along the launch direction. The hollow rotating shaft can pass through a steel rope, allowing the wrapping net 43 to unfold and restrict the target vehicle.

[0089] In a preferred embodiment, this application may further provide a hydraulic telescopic device 31' that can extend along the axis of the rotating arm at the end of the aforementioned rotating arm. After the rotating arm is opened, the winding net constrains the target vehicle, and the winch drives the steel rope to retract the winding net and the target vehicle constrained by the winding net, the end of the hydraulic telescopic device 31' detaches from the end of the rotating arm and extends toward the target vehicle. It can directly abut under the driving wheels of the target vehicle or be engaged with the chassis structure of the target vehicle, restricting the driving wheels or chassis of the target vehicle to remain suspended above the road surface, thereby preventing the winch from being damaged by constantly maintaining a strong pulling force.

[0090] The working process of this vehicle capture device is as follows:

[0091] First, drive the loading vehicle close to the target vehicle, you can refer to... Figure 6The vehicle proceeds to the front of the target vehicle and maintains a safe distance. When the target vehicle reaches the launch range of the telescopic launcher, the driver in the loading vehicle opens the storage device via remote control or a trigger button. This drives the rotary motor to rotate the clamp 302 until it is no longer in contact with the side wall of the positioning horn 301. At this point, the launch spring of the telescopic launcher is released from its limiting pressure, and the wrapping net and steel cable 41 are ejected forward. This allows the wrapping net to wrap around the front wheel or axle of the target vehicle, preventing the axle from rotating and causing the intercepted vehicle to lose its driving power. Subsequently, the operator in the loading vehicle controls the winch to tighten the steel cable 41 via remote control or a trigger button, driving the cable forward to pull the wrapping net, forcing the target vehicle to move closer to the capture vehicle where the operator is located, and dragging the front axle of the target vehicle off the road, thus braking the target vehicle. At this point, the hydraulic telescopic device 31' is further extended backward via remote control or a trigger button to support the front wheel of the target vehicle behind, completing the interception mission. When retracting, the operator only needs to place the wrapping net 43 and steel rope 41 into the storage box 30. All other operations can be performed by reversing the aforementioned steps using the remote control or trigger button to restore the vehicle catcher to its original state.

[0092] In summary, this application can trigger the action component to approach the target vehicle through various forms of pushing devices and constrain the target vehicle's driving wheels, thereby restricting the target vehicle's movement and maintaining the distance between the target vehicle and the loading vehicle in the process. This allows for the interception of a single target vehicle without occupying additional lanes, and without affecting the normal driving of other vehicles on the road.

[0093] The above are merely embodiments of this application, and their descriptions are quite specific and detailed, but they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
